On February 26, Swedish 3D weaving company Biteam has developed a carbon fiber based small-section profiled tapered tube reinforcement for the production of strong and lightweight composite structures.
It is single-walled with a length of about half a meter, a cross-section of approximately 3×3 mm on the front, and a cross-section of approximately 8×3 mm on the rear.
It can be customized to accommodate the right camera or sensor, probe, light source, etc. Such pipes can be connected to drones or robots to inspect aircraft, windmill blades and buildings. Its other emerging uses are robotic fixtures, antennas for space probes, and cores for certain tapered sandwich structures.
When two relatively curved laminates are laid next to each other in the manufacture of composite materials, triangles or triangular cavities will inevitably be generated and need to be properly filled. Current solutions, such as the use of rolled fibers, braids, and cutting reinforcements, are not sufficient to stabilize "laminated" structures and prevent accumulation of unreinforced resin. In addition, they are actually not easy to handle and provide relatively low mechanical properties.
The newly developed dry 3D noodle / filler preform can be customized according to application needs, providing stable cavity matching shapes, good anastomosis, resistance to delamination, no wear, and adapting to different structural needs such as bending. This is the advantage Products that have long been sought to accelerate composite production, improve performance, and reduce labor and inventory costs.
Its relatively small size also allows it to reach inaccessible or hard-to-reach areas. Enhancements can be customized in different ways based on specific application needs.
